Konrad Sprenger's relationship with composer and performer Arnold Dreyblatt has represented an intense meeting of musical generations and genres. Since 2000 Sprenger has collaborated with composer Arnold Dreyblatt in many performances and recording projects, including the production of his current Ensemble. He has also been involved in editing and mixing recordings of Dreyblatt's music, and in the production of many of his sound installation and performance projects.

His own label "Choose Records" has recently issued a retropective LP of live Dreyblatt recordings entilted "Choice" and an LP recording of the current ensemble (which includes Sprenger) is in development. Dreyblatt has initated contacts which have resulted in many of the recordings on Choose and their dialog has extended into many realms of music making and based on years of discussion and collaboration.

Konrad Sprenger has played a pivotal role in the Arnold Dreyblatt Ensemble (now again called "The Orchestra of Excited Strings") which was formed in 2009 for a performance organized by Nymusikk in Oslo , followed by numerous performances in Berlin, Utrecht, Hasselt, Bari, Geneva, Marseille, The Hague and St. Petersburg and Dortmund. In 2014 the Ensemble performed at the MaerzMusik Festival at the Berghain in Berlin. The ensemble performs in two formations, with three or four musicians, including Arnold Dreyblatt on Excited Strings Bass and Laptop; Konrad Sprenger on Percussion and digitally controlled Electric Guitar ; Joachim Schütz, on Dreyblatt's prepared Electric Guitar and often Robin Hayward on microtonal Tuba. A DVD of a live performance has been issued by the Neue Berliner Kunstverein in 2010.
